How don't we have only Na+ inside after several times the nerve is in action? Should be nun out of K+ and only have Na+ left inside the neurone??

Thanks, good explination! But what happens afterward because this time all the K+ is outside and Na+ is inside. The normal position was the opposite (K+ were inside and Na+ were outside).

@PsychExplained

27 күн бұрын

Potassium channels open in response to depolarization, allowing potassium ions to move out of the cell down their concentration gradient. This efflux of potassium ions helps restore the negative charge inside the cell. Sodium channels that opened during depolarization begin to close, reducing the influx of sodium ions into the cell. This decreases the positive charge inside the cell. As a result of these processes, the ion gradients across the cell membrane gradually return to their resting state, with potassium ions predominantly inside the cell and sodium ions predominantly outside. This restoration of ion gradients allows the neuron to prepare for subsequent action potentials and maintain its resting membrane potential.

Why is the voltage at -70 inside at the start? If potassium is positive, what else is in the neuron that's so negative? Great video btw, thank you!

@PsychExplained

27 күн бұрын

The resting membrane potential of approximately -70 millivolts (mV) inside a neuron at rest is primarily due to the differential distribution of ions across the cell membrane, particularly potassium (K+) and sodium (Na+), as well as the selective permeability of the membrane to these ions.

And how does the potassium come back in and the sodium leave to go back to original resting potential? That bit wasn't mentioned. It sounds like in the end, the charge might be the same, but with hardly any K+ And lots of Na+ compared to first charge

@PsychExplained

27 күн бұрын

While the sodium-potassium pump helps restore the original ion concentrations, other mechanisms, such as the closing of voltage-gated sodium channels and the opening of potassium leak channels, also contribute to reestablishing the resting membrane potential.

Sir you explained really well but Kindly tell me why chloride ions didn't play that much role in action potential though they are also present in this process? kindly Explain.

They play a major role at the synaptic bulb (axon terminal). I will touch on this more in my next video on neural transmission ⚡️⚡️⚡️⚡️⚡️

🎯 Key Takeaways for quick navigation: 00:31 *🧠 Understanding Action Potential* - Action potential defined as a brief electrical charge traveling down a neuron. - Neuron anatomy overview: soma, dendrites, axon, axon terminal. - Importance of action potential in neuron communication. 02:23 *🧪 Ion Concentration and Neuronal Resting State* - Neurons surrounded by ions: sodium and potassium. - Resting potential of a neuron at -70 millivolts. - Explanation of the "salty banana" memory technique. 04:01 *⚡️ Excitation and Binding of Neurotransmitters* - Excitation of neurons by stimuli like neurotransmitters. - Role of acetylcholine in binding to receptor sites on dendrites. - Opening of channels for sodium influx upon binding. 06:05 *🎇 Threshold and Action Potential Initiation* - Explanation of the neuron's firing threshold at -55 millivolts. - All-or-none principle: neuron fires when threshold reached. - Activation of voltage-gated sodium channels for action potential initiation. 07:54 *🔥 Depolarization Phase* - Depolarization: neuron becoming more positive. - Sodium influx leading to increased positivity inside the neuron. - Voltage change triggers the action potential. 10:04 *⏳ Repolarization and Hyperpolarization* - Repolarization phase: closure of sodium channels, opening of potassium channels. - Potassium efflux causing the neuron to return to negative polarity. - Hyperpolarization and refractory period before returning to resting potential.

Sir yor explanation of the action potential was very good, but you did not explain how the amount of sodium on the outside and potassium on the inside return to normal.

@PsychExplained

Ай бұрын

Repolarization - brings the cell back to resting potential. The inactivation gates of the sodium channels close, stopping the inward rush of positive ions. At the same time, the potassium channels open.

How you get awareness out of this unconscious matter ?

So, the transmission of the action potential is like an electric canon

you are so unique please keep it up but i have a question why the + and _ charge interchange and where is the _ charge comes ? both K+ and Na+ are positive how exchange meaning when Na + inter the k+ out HOW ??? i public health student and i want to be know more about this

@PsychExplained

27 күн бұрын

Hello! Not sure I understand your question - In the case of the sodium-potassium pump, which is essential for maintaining the resting membrane potential of nerve cells and muscle cells, sodium ions (Na+) are pumped out of the cell while potassium ions (K+) are pumped into the cell.

Is the Refractory period part of the repolorization?

@PsychExplained

11 ай бұрын

Great question. I would say no. These are separate events. Order: Resting state --depolarization-Repolarization --hyperpolarization (refractory period). Repolarization is part of the firing process of a neuron, while the refractory period deals with a neurons ability to generate another action potential.

I dont think its right to put only minus or positive inside the neuron, there is both positive and negative always outside and inside the neuron. Just the amount changees.
